Abstract
A user device transmits data at a first transmit power level. The user device detects a presence of a human body part within a predetermined distance from an antenna of the user device using one or more sensors disposed at a back side of the user device. In response to the detection of the presence of the human body part, the user device transmits information at a second transmit power level that is less than the first transmit power level.
